SPECIFICATION forming part of Letters Patent No. 281,204, dated July 10,1883.

Application filed November 18, 1538-2. (No model.)

To a'ZZ whom it may concern:

. Be it known that we, MICHAEL RUNsTETLnR A and ANDREW RUNSTETLER,citizens of the United States, and residents of Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and usefulImprovements in Corn-lilanters7 oi' which the following is aspecification.

Our invention relates to the construction of corn-planter frames.

The object of our invention is to construct the frame of acenter-coupled corn-planter of tubular iron, and so combining the partsthat the wheels and seed-boxes can be readilyl adjusted laterally towiden or narrow the distance between the rows, as occasion may require,without disturbing the connections of the frame. all of which will befully explained in the accompanying drawings, in which--A Figure l is aplan view of a corn-planter embodying ourinvention, hut showing amodiied form of link or arm connecting the main and runner frames. Fig.2 is a sectional elevation on line :r at, Fig. l, showing the rear ofthe runner-frame. Fig. 3 is an enlarged sectional frontelevation, takenon the line y y, Fig. l, with the hoppers removed and the dropper-plateand one of the tubes of the runner-franxe-broken off. Fig. 4 is an endeleva tion of the runner-frame with the reach and tongue removed to showthe manner of mounting the hoppers and runners on the hollow frame-bars.Fig. 5 is an enlarged sectional eleva-tion on line z e', Fig. l7 showingthe same modified link for connecting the main and runner frames, andthebracket-bearings for journaling the crank-lever which drives thereciprocating dropper-bar; also shown in crosssection. Fig. is a detailperspective view of one of the detachable bracket-bearings forjournaling the crank-lever, in this instance the rear one, shown in Fig.5. Fig. 7 is adetail perspective view, showing the otherbracket-bearing, in this instance the forward one, shown in Fig. 5. Fig.S is an enlarged central longitudinal section of the forward end of oneof the reaches or hounds7 showing the manner of coupling it with theforward tubular bar of the runner-frame. Fig. 9 is a detail perspectiveview of one of the semicircular couplings for uniting the various partsof the round-iron frame. Fig. 10 is an enlarged longitudinal section,partially inl elevation, showing the manner of adjustably mounting thegroundwheels of the machine on one end of the axle and the sprocket fo rdriving the dropper incohanism. Fig. ll is an enlarged detailperspective view of the coupling-block, shown in section in Fig. 10, foruniting the main frame and the supporting-axleoi' the machine.v Fig. l2is an elevation of the broken end of the supportingaxle, showing themanner of adjustably mounting one of the ground-wheels thereon. Fig. 13is an enlarged sectional elevation on line g/ y', Fig. l, showing themanner of connecting the rear end of the hounds on the runner-frame withthe raising and lowering devices on the main frame. Fig. 14 isa detailperspective view, showing the couplingbracket for connectingthe houndsofthe runner-frame with the raising and lowering devices on the mainframe, the same as that shown in Fig. 13. Fig. l5 is a detail plan ofbroken parts of the runner and main-frame bars,.showing the preferredform of link for uniting them together.

A A represent the side rails of the main frame, which are made oftubular iron, united to a tubular end rail by means of pipekneecouplings a. a..

B represents a stationary axle on which the ground-wheels B arejournaled.

b b represent semicircular coupling-blocks having circular faces b b"7as shownV in Fig. ll, into which the tubular parts A A and Brespectively fit, and which are rigidly united together by means of ascrew-bolt7 c, thereby forming a light and durable main frame.

C represents the hub of the wheels B', which 'is attached rigidly tosleeve C7 which journals on the axle B.

C represents a sprocket drivingwheel con nected to sleeve C andrevolving with wheel B for operating the dropping devices.

c' represents a pin for preventing lateral movement of sleeve C..

c represents a setscrew passing through hub C for securing wheel B inposition, and to allow of an easy lateral adjustment of the wheel on theshaft to widen or narrow the dis- IOO 1o wheel.

The runner-frame is composed of tubularcross-rails E E E andlongitudinal hounds F F, which are rigidly connected to the crossrailsby means of semicircular couplings e e', each of which is formed asshown in Fig. 9, o

representing a boss or bearing, so that when the two couplings arejoined they may be readily adjusted to each other and to the plane ofthe tube, and secured firmly together by I zo means of a screw-bolt.Hounds F F are shown approaching each other as they extend rearwardlytoward the main frame, so as to better brace thevrunner-frame; but theycanv be placed in parallel planes.

ends to the front rail, E.

top of standard G.

which pass the cross-rails E E.

i i represent set-screws tapping the sleevecouplings g and f foradjusting the runners and seed-boxes laterally on the pipe-rails andsecuring them in any desired position.

I represents a coupling-arm having a sleeve or circular bearing at oneend, fitting upon rail E, to which it is rigidly bolted, and forked atthe opposite end, through which forks passes abolt, j, uniting thecoupling to slotted bracket J, which is fastened to side rails, A A, as

shown in Figs. 1, 5, and 15. It is obvious that the brackets J might beforked, instead of the coupling-arm I. Brackets J might also be made tofit around rail A, instead of inside, as 5o shown.

K, Fig. 141., represents a standard provided with curved coupling-joints F, fitting the tubular hounds F F. rIhe shank end 7c is forked andpivoted in the slot of treadle L. The sleeve and treadle are preferablyconstructed as shown in Letters Patent No. 259, 054, granted February21, 1882.

M represents the shaker-rod, which is connected to the reciprocating.dropper-bar M 6o by means of coupling-arms m m, which are provided witha sleeve passing over rod M and secured by set-screws. This mode ofconnecting the dropper-plates is very convenient, as it allows the throwof the bars M to be read- 6 5 ily adjusted to accommodate the differentwidths to which the machine-runners may be set apart. This rod M is ofsufficient length The bearingi sleeves D D are held in position byset-screws d, which allow of the lateral adjustment of the toaccommodate the widest adjustment, and by making an offset in thevarms mit extends under the dropper plates M. It is also adapted to anycorn-planter, as the throw of the rod M by this means can be nicelyadjusted to any dropper device employed.

N N represent j ournal-brackets secured to hounds vF F and providedwitheye-bearings n, in which crank-shaft N journals.

l? represents a coupling journal-bracket attached to rail E, and uponwhich the gears Q R are journaled, and which gears are drivenby'sprocket-wheels S and G.

rIhe mode of constructing and operating the remaining parts of thedropping devices, and the mode of constructing and operating theelevating and depressing lever, have been fully shown and described inprevious Letters Patent granted A. RUNsTE'rLER and M. RUN- sTETLER, andwill not be Aherein described.

Coupling-blocks b, instead of being made of one piece, could be made oftwo pieces, of the form shown in Fig. 9, and the rails joined, as

1 shown at e e', Fig. l. So, too, when hounds f f represent runners ofthe usual form, and r f f sleeve-couplings for securing their front F Fare constructed to be in parallel lines, a solid coupling, b, might beused instead of the duplex parts e e; but the latter is the .easiest Grepresents the seed-boxes, which are rigidly attached to the standardsG" of the run- 3o ners f by means-of a bolt connecting bracket,- g ofthe seed-box to ange h, formed at they mode of fitting and adjustment.

By making one side of the coupling b journal-boxes a revolving axlecould be employed instead of a revolving sleeve, in which case thedriving-wheels should be made fast to the g `g representsleeve-couplings rigidly se- 1 cured to flange h of standard G', andthrough axle itself. rlhe laxle is shown as made solid. 10o It can bemade tubular, if desired.

The semicircnlar form of coupling-blocks, connecting the tubular partsby through-bolts, provides a ready means of adjusting the connectedrails, as well as allowing the ready removal of any one of the partswithout taking the entire frame apart.

We claim- 1. A corn-planter having the main or riding frame constructedof tubular rails united together and connected to the axle by means ofbolts and semicircular coupling-blocks, substantially as herein setforth.

2. In a corn-planter, the front runner-frame, composed of tubularcross-rails and longitudinal tubular hounds, connected together by meansof semicircular coupling-pieces e or their described equivalents,substantially as herein set forth.

3. In a corn-planter, the tubular main and runner frame, coupledtogether by means of connecting-arms I, and brackets J, adapted ltoconnect the tubular partsof said frames, substantially as herein setforth.

4. In combination with the tubular hounds F F of the runner-frame, thecoupling-standard K, having the semicircular coupling-arms and united bythrough-bolts, connected to the hounds and hinging them to the treadleL, substantially as herein set forth.

5.
